DOUBLE-REGlPRQOMTlNG- DASi-iER CHURN.

SPECIFICATION forming part of Letters Patent No. 755,373, dated March22, 1904:.

KNo model.)

To (all whom it may concern.-

Be it known that I, EDMUND M. KYLE, a citizen of the United States ofAmerica, residing at North Belle Vernon, in the county of VVestmorelandand State of Pennsylvania, have.

invented certain new and useful Improvements inDouble-Reciprocating-Dasher Churns, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in churns,and relates more particularly to that type known asdoublereciprocating-dasher churns, the invention having for its objectthe provision of novel means for operating the two dasherssimultaneously and alternately in the receptacle, and, furthern'iore, toprovide means whereby the operating-handles may be rotated to impart areciprocatory movement to the dashers or operated with a doublereciprocating movement, as may be desired.

My invention is an improvement on my Patent No. 713,891, issued November18, 1902; and one of the objects of the present in vention is tomateriallysimplify and chcapen the cost of construction.

Briefly described, the invention comprises a churn-body or receptacle inwhich a pair of dashers are adapted to be reciprocated alternately. Thedriving means in the present invention for reciprocating thesedasherscomprises a pair of cranks carried by a common shaft, which shaftjournaled in a bearing carried by the coupling member through which bothof the dasher-rods operate, this coupling member being supported bybracerods attached at their loweriend to the frustoconical shield, thelower edge of which fits into the upper end of the churn-body orreceptacle and which? carries a rim that fits around the outer side ofthe churn-body or receptacle, at the top thereof, and locks the shieldand other parts in proper relation. The cranks are set at the half withrespect to each other and are connected by the coupling ence is had tothe accompanying drawings, forming a part of this application, andwherein like numerals of reference indicate like parts throughout theseveral views, in which- Figure 1 is a side elevation of a churnconstructed in accordance with my invention. Fig. 2 is a centralvertical sectional viewthere of. Figs. 3 and 4: are detached detailperspective views of the two members of the coupling through which therespective dasher-rods 0perate. Fig. 5 is a detached detail perspectiveview of the clamp or clevis member of the coupling. Fig. 6 is atransverse vertical sectional view of a part of the coupling and of theshaft. Fig. 7 is a detail perspective view of one of the dashers,showing the dasher-rod broken away. Fig. 8 is a detail perspective viewof the lid of the churn.

To put my invention into practice, Iprovide a churn-body or receptacle1, which may be of any desired form of construction in the main and isprovided with a suitable lid 2, having a handle 3 and openings at 5therethrough, this lid being adapted to fit neatly in the upper end ofthe churn-body or receptacle. 1n practice I have generally constructedthe churn-body so tl at the lid when in position lies slightly below theupper end of the staves of the churn-body or receptacle, which extendingportion has a bevel-seat 6, adapted to receive the lower end or edge ofa substantially frusto-conical shield 7, which is carried by a securingband or hoop 8, being suitably connected thereto, as by straps 9, formedintegral with the securing band or hoop 8 and riveted or otherwisesuitably secured to the shield 7. The securing band or hoop 8 fitsneatly around the uppermost hoop of the churn-body or receptacle and islocked in poby to decrease friction with the drive-shaft 22. Thisdrive-shaft 22 is provided with cranks 23, set at the half with respectto each other and the drive-shaft and provided with suitable handles 24.One sleeve 16 receives dasher-rod 15, and the other sleeve 16 receivesdasher-rod 14, and the coupling is supported at each side by means ofbrace-rods 25, brought together and joined at their upper ends andprovided with eyes 26, that register with the openings in plates 17 andalso with openings 27 in the side straps 28 of a clevis 29, whichstraddles the plates 17 and members 18 of the coupling, as seen in Figs.1 and 2, and the parts are securely fastened and held by bolts or rivets30.

To the dasher-rods 1 1 15 are secured near their upper ends sleeves 31,which may be securely held by pins 32, passed through the sleeves anddasher-rods, or in other desirable manner. Thesleeves are formed of asheet of material bent into circular form, with the edges broughttogether and bent outwardly, and these edges are provided approximatelycentral of their length with lugs 33, apertured to receive the upper end34: of the links 35, which connect'the sleeves to the cranks 23,

the said links having strap ends engaging said cranks. The upper ends ofthe links are secured to the sleeves 31 by bending said ends at rightangles and passing them through the apertured lugs and then heading theends. It will of course be evident that this particular construction maybe varied. In practice the links are usually of the form shown herein, aportion of the same being straight and the upper portion bent in towardthe dasher-rods in order that a better pivotal connection may be hadwith the sleeves 31. The lower ends of the brace-rods 25 are preferablyriveted to the shield 7 and when the shield is lifted or elevated fromthe churn-body or receptacle the coupling slides up on the dasher-rodsunless the latter are lifted with the lifting of the shield.

In operation it will be observed that when the cranks are rotated one ofthe dasher-rods and dasher will be driven down ward while the other isbeing elevated, and vice versa. The cranks may, as will be observed, bereciprocated to impart the same movement to the dasher-rods and dashers.The links and cranks will always retain their relative position towardone another irrespective of the position or direction in which they arerotated or reciprocated, and two persons may operate the churn, eachactuating one crank. lower edge of the shield extending into thechurn-body or receptacle and the shield being rigidly secured to thesecuring band or hoop embracing the churn-body or receptacle, thecoupling is always properly alined with the openings 4 5 in the lid, andthe provision of the antifriction-bearings in the bearing makes thecranks easy to operate.

In the accompanying description of my invention I have described andhave shown a practical embodiment of the invention as it has beenpracticed by me; but it will be evident that various slight changes maybe made in the details of construction without departing from thegeneral spirit of the invention.

Having fully described my invention, what I claim as new, and desiretosecure by Letters Patent, is

1. A churn comprising a churn-body or receptacle having a lid providedwith openings, a shield fitted in the upper end of the churnbody orreceptacle and secured to the periphcry of said churn-body, brace-rodssupported by said shield, a coupling supported by said brace-rods andprovided with a pair of sleeves, a' shaft journaled in said coupling andhaving a pair of cranks, dasher-rods operating through said sleeves andcarrying dashers operating in the churn-body, and links pivotallyconnected to the cranks at one end and to the dasher-rods at the otherend, substantially as described.

2. A churn comprising a churn-body or receptacle having a lid providedwith a pair of openings, a frusto-conical shield fitted in the upper endof the churn-body or receptacle, brace-rods secured at their lower endsto said shield, a coupling secured to the upper ends of said brace-rodsand having sleeves alining with the openings in the lid, a shaftjournaled in the coupling and provided with antifriction-bearings,cranks carried by said shaft, and links connected at one end to thecranks and at their other end to dasher-rods, and dasher-rods operatingthrough said sleeves and openings in the lid, and provided on theirlower end with dashers, substantially as described.

3. A churn comprising a churn-body or receptacle provided with a lidhaving a pair of openings, a supporting-shield engaging in the upper endof the churn-body or receptacle, a securing-band connected to saidshield and embracing the periphery of the churnoody at the top thereof,a coupling supported from the shield and provided with a pair of sleevesalining with the openings in the lid, dasherrods operating through saidsleeves and open- The e ings and provided with dashers on their lower Intestimony whereof I alfix my signature in ends, a shaft journaled in thecoupling and the presence of two Witnesses. havlng cranks on its endsset at the half with EDMUND M. KYLE respect to each other, sleevessecured to the dasher-rods above the coupling, and links con- Witnesses:
